Sunshine
The amount of sunshine Durban receives is
related to the amount of cloud cover. In winter,
with the persistence of high pressure systems
and cloud-free skies, Durban receives 60-70% of
possible sunshine. In spring and summer this
figure drops to 50% of possible sunshine as
cloud cover builds up.
Radiation
The receipt of solar radiation by Durban
varies between seasons ranging from 1.13 x
10
7 Jm-2 day-1
in June to 2.14 x 10 7 Jm-2
day-1 in January. Many people
in Durban are involved in outdoor recreational
activities which increases their exposure to
harmful UV-A and UV-B radiation potentially
causing cancer and eye
cataracts.
